Is it any better in .NET based on your experiences? I have been working on a multiple project workspace(about 25 projects in a workspace) and more often than not the dialog boxes give you a headache. Is it any better in .NET? unzip smooth3-Aug-02 15:41 smooth 3-Aug-02 15:41  how could i unzip .zip files to a user entered dir in mc++ Re: unzip James T. Johnson4-Aug-02 13:35 James T. Johnson 4-Aug-02 13:35  The same way you do it in regular C++, find or write a ZIP unpacking library and use it. Not much of an answer but its the truth There are various ZIP libraries out there; one is available at icsharpcode.net[^] according to the site it is GPL'd but the site also says at the bottom that you can use it in a closed-source app. James "Java is free - and worth every penny." - Christian Graus Re: unzip Shog98-Aug-02 18:25 Shog9 8-Aug-02 18:25  James' solution is of course the correct way, but if you (like me ) are lazy, you can instead just download Info-Zip and spawn it to do your bidding. Less flexible, and not completely .NET of course, but still a useful technique if your needs are modest... --- Shog9 If I could sleep forever, I could forget about everything... Error code (0x80131019) ?? Firoz2-Aug-02 1:09 Firoz 2-Aug-02 1:09  Hi, I created a CustomConrol using ManagedC++. This Control is Used in a C# Application. When I Drop/Draw this Control to a Form, I get an error message "Exception from HRESULT : 0x80131019". But when I set the CopyLocal property of the Reference to False, the Control is properly Drawn. Why does this happen. Why it gives Error when CopyLocal is True? What does the Error code (0x80131019) mean ? (I was not able to find this HRESULT Code in WinError.h) Thanks, FiroZ " denotes a field where a class was expected" Anonymous30-Jul-02 22:52 Anonymous 30-Jul-02 22:52  Can any body help me!!!

Christian Graus29-Jul-02 19:00 Christian Graus 29-Jul-02 19:00  Does SetItemData put hidden information in ? I don't recall seeing anything similar to that. I know for items that are visible you need to create a new instance of an item or subitem and then pass it in, but I don't think it has a data field.

Nish Nishant29-Jul-02 19:19 Nish Nishant 29-Jul-02 19:19  Blast!!! Say I have a listbox with the following stuff apple orange grapes orange banana apple Notice how apple and orange appear twice. Now to internally differentiate these items [because they are the textual casts of a more complex actual object] I'd need to associate an id with each. apple [ap1] orange [or1] grapes [grp] orange [or45] banana [bnna] apple [ap6] See? How do I do that??? Regards Nish p.s. The intention is this. If the guy has selected an item that appears multiple times, I should be able to get the id associated with it!

Re: CListBox::SetItemData equivalent? Christian Graus29-Jul-02 19:56 Christian Graus 29-Jul-02 19:56  I dunno, given that the Win32 boxes do it, you'd think it was possible. If not, could you put the data in another column and hide it, by forcing it to be 0 pixels wide ? I'll be home in two hours, if there's no other answer by then, I can check in Petzold.

Nick Hodapp9-Aug-02 14:35 Nick Hodapp 9-Aug-02 14:35  The ListBox control can contain any Object derived class, not simply strings. To display a value, ListBox calls the Object::ToString(), which you can override on your own types. This means that you can insert items that contain more than 32bits of "Item Data". Note for ListViews, use the ListItem "Tag" property to store user-information (of any type). This posting is provided “AS IS” with no warranties, and confers no rights.

MFC container classes are such crap, why would they specialise such a thing ? Anyhow, the answer is dictionarybase, a class you need to derive from in order to create a dictionary which is strongly typed. There's heaps of docs in MSDN, basically the derived class gets access to a member called Dictionary, if you derive a class from DictionaryBase, and then type Dictionary., the autocomplete makes the rest of it pretty self explanatory. It is NOT a multimap though, if you use the put method and try to put a key that already exists, it will blow up, and if you use the [] notation, the new value will overwrite the old one.
